IMPROVEMENT IN WASH-BOILERS.

To all whom it may concern:

Be it known that I, WILLIAM G. GIBSON, of Lynchburg, Highland county, State of Ohio, have invented certain new and useful Improvements in Wash-Boilers, of which the following is a specication:

Nature Objects of Invention.

My invention relates to the class of washboilers in which the water is caused to circulate forcibly and automatically; and consists of peculiar devices for giving the-Water a higher velocity than heretofore attained, and rendering the motion of the same uniform throughout the entire area of the boiler.

Description of the Accompcnyl'ngDmw-ing.

Figure lis a longitudinal section of my wash-boiler, and Fig. 2 is a perspective view of the detachable circulator.

General Description.

A is the body of the boiler and B, the cover of the same. `The latter has fitted to it screwthreaded tubes b b provided withl caps cc to match. By the removal of one or both of these caps when the Water in the boiler is excessively heated, the steam may be permitted to escape sufficiently to save the necessity of taking the lid of the boiler off. By retaining the cover B on the boiler, and allowing the steam to escape by the small openings b b', more water can be used in the boiler than is possible with the cover ol without boiling over, and the water can also maintain a higher temperature without excessive `ebullition. The circulating device of my improved boiler consists of the crowning-plate C, which forms, by reason of its flexible crowning configuration, a self-fastening false bottom to the boiler for the clothes to rest upon. The false bottom C, in order to make its flexible character available for self-fastening, is made a little wider than the width of the boiler, so' that it may be sprung into place, and thus held by forcible contact with the sides of the boiler. It may also rest, as shown, upon the outer edges of the boiler-bottom, the crowning shape of the false bottom giving ample space below it for the passage of water Vin l l circulation, which is received thr nl gh the perforations d of the plate (l. Firm the plate O is a central circulat whose lower endhas a funnel-sh d', which collects and directs th ter in such a way as to induce sage of Water up the tube D, and descent of water through the pte O. The upper end of tube D is closed, shown, and the exterior of it near the upper l d provided with an annular inverted trou 1, E, which acts as a directing-chute for a p tion of the discharged Water. Perforation-` c are provided in the tubeD above the ute E, and perforations c below it. The 1 rforations c direct the water to the eXtrem .portions of the boiler, and also equally to t surface of ped mouth, ihottest wa- .i liolent pasconsequent the boiler nearer the center. In irectin g the i water to the central portion oft x boiler, the perforations c and the chute E a employed, the chute confining the distrib tion of the water to the portion of the boil` which the streams from the perforations overreach. Suspended from the top of the ,pipe D is a closed tube or solid cylinder, F, hose lower end is conical, as shown. This rves, by reducing the area of the interior correspondingly increase the v` water through it. The conical en of cylinder F oIlers less obstruction to the ee entry of the water than any other form.

Claims.

1. The combination, in a wahboiler, of crowning-plate C, tube D d', inv` ted trough or chute E, and perforations e le', arranged and operating substautiallyin th :manner and for the purpose specified.

2. In the described combinat n with the elements of the clause immediate preceding, the conical=ended cylinder F, a ranged and operating substantially in the m ner and for the purpose specified. l

In testimony of which inventi set my hand.
